There are some television shows that have a fashion ripple effect. Sex and the City had it in spades, while Dynasty made shoulder pads and ozone-holing levels of hairspray practically obligatory in the 1980s.

Gossip Girl is the noughties equivalent. There is something for every fashion personality - slightly dishevelled bombshell (Serena); Upper East Side ingénue (Blair) or “found your outfit in a bin behind a strip joint” chic (Little J). For those who like a little androgyny you can even take tips from Chuck Bass.

This season, having made it to Columbia and into the co-ed social club Hamilton House (obviously I never watch the show…), Blair and Serena have been sporting the House’s sought-after keys around their necks. I liked the detail, liked that the girls were wearing them on different chains - I’m sure I saw Blair wearing her hanging of a strand of pearls one episode, but, like I say, I don’t really watch it.

I thought it just might be something the jewellery industry would be cottoning on to next year. So you can imagine my fashion excitement when I went to the Guess press day and saw keys on pieces. It confirmed my personal trend predictions.

I may not live on the Upper East Side, have access to a parental bank account that allows me to spend a small fortune in Celine, but I am certainly going to be working the key trend next year. And I am sure many Gossip girl acolytes will be wanting to as well. You might want to stock up on some now.
